Specification of Letters Patent.

Application filed November 9, 1912.

T 0 all whom, it may concern:

Be it known that I, TVILLIAM P. SIBLEY, a citizen of the United States, residing at Abilene, in the county of Taylor and State of Texas, have invented a new and useful Churn, of which the following is a specification- The device forming the subject matter of this application is a combined churn and cooler.

One object of the invention is to provide novel means for lifting a cooling liquid out of a tank and for discharging the liquid upon the outside of the churn receptacle.

The invention aims, further, to provide novel means for discharging a blast of air around the churn receptacle. It is within the scope of the invention, to provide novel driving mechanism for actuating the movable parts of the structure. I

\Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed it being understood that changes in the precise embodiment of invention can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing :Figure 1 shows the invent-ion in side elevation; Fig. 2 is a transverse section on the line 22 of Fig. 1; and Fig. 3 is an elevation showing a portion of the speed controlling mechanism.

In carrying out the invention there is provided a case 1 supporting standards 2 and 3,

the standards serving to uphold an intermediate platform 4. Fixed to and rising from the intermediate platform 4 are standards 5 and 6, supporting an upper platform 7. Standards 8, 9, and 10, supported by the platform 7 serve to uphold a table 11.

Mounted upon the standards 2 and 3 is a blower casing 12, provided with an inlet 14 and an outlet 15 discharging through an opening in the standard 3. Secured to the outer face of the standard 3, or located adjacent the standard 3, is a tank 16 provided with a drain cook 17. Alined vertically with the side wall of the tank 16 is a transversely curved deflector 18 through which the outlet 15 discharges. Journaled for rotation in the blow-er casing 12 is a shaft 19,

carrying a plurality of blades 20, adapted to suck air inwardly into the casing 12 through the inlet 14, and to discharge the air through the outlet 15. Secured to one end of the shaft 19 is a beveled pinion 21, meshing into a beveled pinion 22, secured to a shaft section 23, journaled for rotation in a bearing 24 secured to one side of the blower casing 12. The upper end of the shaft section 23 is received within the sleeve 25 for rotation. The upper end of the sleeve 25 receives for rotation a shaft section 26, j ournaled in a bearing 27 secured to one edge of the intermediate platform 4. Set screws 28 are threaded into the sleeve 25, to the end that the shaft sections 26 and 23 may be disconnected when desired. Securedv to the upper end of the shaft section 26 is a beveled pinion 29.

The beveled pinion .29 meshes into a beveled pinion 30, the hub 31, of which is secured to a shaft 32, journaled in uprights 6 and 5. The inner end. of the hubcarries a clutch member 33 cooperating with a clutch member 34 operatively connected with a barrel 35 which is j ournaled on the shaft 32,

the clutch member 34 being controlled by a clutch lever 36. Secured at one end to the barrel 35 is a coil spring 37, one end of which is secured to a pin 38 projecting inwardly from the upright 5. Secured to the shaft 32 is a ratchet head 39, abutting against a frame 40 which outstands from the upright 5. A lever 41 is fulcrumed as indicated at 42 upon the upright 5, the lower end of the lever 42 being provided witha ratchet head 43 which is adapted to engage with the ratchet head 39 of the shaft 32.

The beveled pinion 30 meshes into a beveled pinion 44, secured to the lower end of a vertical shaft 45.

head 47 is a yoke 51, supporting counterweighted arms 52, connected by a downwardly curved spring 53 through which the upper end of the shaft 45 passes, there being 5 a boss on the upper end. of the shaft 45,

the boss engaging the spring 58, so that when the spring 58 is stretched out by the action of the arms 52, the shaft 45 may be elevated. Projecting laterally from the shaft 45 is a curved shoe 55, which may be 5 shaft 45 rotates in the shoe 55.

A beveled pinion 58 is supported by the platform 7, the shaft 45 being free to slide longitudinally of the pinion 58, the pinion 58 and the shaft 45 being splined together,

so that "when rotatory movement is imparted to the shaft 45, the pinion 58 will rotate also. The spline connection between the pinion 58 and the shaft 45 is indicated at 59. The pinion 58 meshes into a beveled pinion 60, secured to the shaft 61, journaled in the uprights 9 and 10. Secured to the shaft 61 is a beveled pinion 62, meshing into a beveled pinion 63, secured to the upper end of a shaft 64, the lower end of which is received within a sleeve 65, the sleeve 65 receiving the upper end of a shaft section 66. Set screws 67 are threaded into the sleeve 65, the set screws 67 engaging theshaft sections 66 and 64, to the end that these sections may be connected and disconnected when desired. Secured to the lower end of the shaft section 66 is a pinion 68, meshing into an internal gear 69, secured to the upper end of a receptacle 70, the

lower end of the receptacle 7() being journaled for rotation in a thrust bearing 71 which is mounted upon the bottom of the tank 16.

The extremity of the shaft 61 carries a beveled pinion 72, meshing into a beveled pinion 73, secured to the upper end of a shaft 74. The shaft 74 is journaled in the platform 7, the shaft 66 being journaled in the platform 7 and in the platform 4. The

lower end of the shaft 74 is received within a sleeve 75, the sleeve 75 receiving the upper end of a shaft section 76. Set screws 77, threaded in the sleeve 75, serve to connect the shaft sections 74 and 76 operatively.

The lower end of the shaft section 76 enters the receptacle 70, and carries a dasher 84, which may be of any desired form.

Secured to one end of the shaft 32 is a wheel 7 9, connected with a pitman 80, the

lower end of which carries a yoke 81, sup

porting pivotally a dipper 82, the dipper 82 being adapted to descend into the tank 16. Connected to the receptacle is a ring 83. The ring 83 is disposed in the path to of the dipper 82, to the end that when the dipper 82 is elevated, the dipper may engage the ring, thereby effecting a spilling of the contents of the dipper upon the outside of the receptacle 70.

In practical operation, the spring 37 will actuate the barrel 35, the barrel being operatively connected with the hub 31 of the beveled pinion 30 through the instrumentality of the beveled pinions 62 and 68, ro-

tation will be imparted to the shaft 6466, the shaft 64-66 driving the pinion 68 and the pinion 68 imparting rotatory movement to the receptacle 7 0, through the medium of the internal gear 69, the receptacle 70 rotating upon the thrust bearing 71. lVhen the shaft 61 is rotated, motion will be transmitted through the beveled pinions 72 and 73 to the shafts 74 and 76, the dasher 84 being rotated within the receptacle 70. From the beveled pinion 30, motion will be transmitted into the pinion 29 and thence,

by way of the shafts 26 and 23 to the beveled pinion 22 and into the beveled pinion 21, motion being imparted to the shaft 19 and the blades 20 of the blower being actuated.

lVhen it, is desired to disconnect the blower mechanism, one of the set screws 28 may be loosened, thereby disconnecting the shafts 26 and 23. operate the structure without causing a rotation of the receptacle 70, one of the set screws 67 may be loosened, thereby breaking the operative connection between the shaft sections 64 and 66. sired to operate the structure without causing a rotation of the dasher 84, one of the set screws 77 may be loosened, thereby permitting the shaft 74 to rotate, without rotating the shaft 76.

Should it be desired to cause the rotation of the receptacle 70 and the rotation of the dasher 84 to cease, simultaneously, the screw 50 may be rotated, tilting the lever 48, the lever 48 engaging the head 47 and lifting the shaft 45 so that the pinion 44 is no longer in mesh with the pinion 30.

In order to stop the entire mechanism,

when the spring 37 is under tension, the

lever 41 is tilted. to spring the ratchet head 43 of the leverintoengagement with the ratchet head 39 which is fixed to the shaft 32, the clutch members 33 and 34 being in:

lVhen it is desired to When it is de-' dium of the spring 37 the ratchet head 33 of the lever 41 is disengaged from the ratchet head 39 of the shaft 32, the clutch member 34 being disengaged, through the medium of the lever 36, and from the clutch member 33. Whereupon, direct manual rotation may be applied to the pinion 30.

I/Vhen it is desired to wind up the spring 37, the clutch members 33 and 34 are interengaged, the shafts 26 and 23 are disconnected, and the lever 48 is tilted to draw the pinion 44 out of mesh with the pinion 33. Thereupon, the shaft 32 may be rotated, the same, through the medium of the clutch members 33 and 34 actuating the spring barrel 35, tension being held by the interengagement between the ratchet head 43 of the lever 41 and the ratchet head 39 of the shaft 32.

When the blower 1220 is in operation, air will be sucked into the casing 12 through the inlet 14, the air being discharged out of the casing 12 through the outlet 15 and into the deflector 18, the deflector 18 directing the air around the periphery of the receptacle 7 0.

IV hen the shaft 32 is rotated, the wheel 79 will actuate the pitman 80, the pitman 80 through the medium of the yoke 81 elevating the dipper 82. The dipper, filled with liquid from the tank 16, will abut against the ring 83, whereupon the dipper will be tilted the contents of the dipper being discharged upon the outside of the receptacle 7 to effect a change in the temperature of the contents of the receptacle, it being understood that by drawing liquid out of the tank 16 by way of the cook 17, and by adding a refrigerating substance, or a heating substance, the temperature of the contents of the tank may be regulated.

Should the shaft 32 acquire an unduly high speed of rotation, this speed transmitted to the shaft 45 through the medium of the pinions 30 and 44 will be transmitted to the head 47 and to the yoke 51, the arms 52 swinging outwardly, causing a straightening of the curved spring 53, the spring 53, engaging with the head 54 of the shaft 45 and causing an elevation of the shaft 45. \Vhen the shaft 45 is elevated, the pinion 44 will be withdrawn out of mesh with the pinion 30. At the same time, the shoe 55 will be carried upwardly into engagement with the inclined face 56 of the rim 57 of the pinion 30, a braking pressure being thus applied to the pinion 30. hen the speed of rotation of the shaft 32 decreases, the shaft 45 will move downwardly, bringing the pinions 44 and 30 into mesh.
